Examining what graphs do at their ends like this can be useful if you want to extrapolate some new information that you don't have data for. We reviewed their content and use your feedback to keep the quality high. y ultimately approaches positive infinity as x increases. 5. Generate polynomial from roots is equal to negative four, we probably want to have a term that has an x plus four in it. Write an equation for the polynomial graphed below Therefore, to calculate the remainder of any polynomial division, it is only necessary to substitute (a) for (x) in the original function. Each x-intercept corresponds to a zero of the polynomial function and each zero yields a factor, so we can now write the polynomial in factored form. The x-axis scales by one. With a constant term, things become a little more interesting, because the new function actually isn't a polynomial anymore. Using the Factor Theorem, the equation for the graphed polynomial is: y (x) = 0.125 (x + x - 14x - 24).
